Description
Affiliated technical field:
The utility model relates to equipment, especially vertical combined sieving device that a kind of industrial material is classified by granule size.
Background technology:
In the prior art, technique known is, the applicant is in State Intellectual Property Office's application and disclosed No. 02109925.1 patent, this patent disclosure a kind of vibratory sieve take less ground method and the technical scheme of vibratory sieve, the vibratory sieve of this scheme be adopt a plurality of sieve units in screen box by on, the following layout, tail, the vibratory sieve that head Z font is relatively from top to bottom arranged, this structural vibrations sieve is owing to be three-dimensional up-down structure, therefore, ground can be taken less, and the purpose of screening can be reached, but to the inventory of needs screenings when big, just there is the lower defective of screening efficiency in this structural vibrations sieve, and this is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model, be exactly at the existing in prior technology deficiency, and provide a kind of vertical combined sieving device technical scheme, this scheme adopt by one in seal casinghousing on the compass screen surface splayed that constitutes of unit screen cloth arrange sieve unit and the compass screen surface that the lower unit screen cloth constitutes in seal casinghousing is that the following sieve unit that herringbone is arranged is formed a sieve unit, be arranged above and below by a plurality of sieve unit again and form multistage sieve, this structure is owing to also be stereochemical structure up and down, so can take ground less equally, but the efficient of its screening significantly improves.
This programme is realized by following technical measures: the vibrator that includes seal casinghousing and fix on seal casinghousing, on seal casinghousing, also has exhaust outlet, on seal casinghousing, be connected with oversize discharge nozzle and minus mesh passage, at the seal casinghousing inner chamber screen cloth and distributing device are arranged, the characteristics of this programme go up sieve unit by one and a following sieve unit is formed a sieve unit, be arranged above and below by a plurality of sieve unit and form multistage sieve, perhaps, by a plurality of sieve unit and following sieve unit or on sieve unit be arranged above and below and form multistage sieve; Described go up sieve unit be in last unit seal casinghousing on the compass screen surface that constitutes of unit screen cloth be the splayed arrangement; Described sieve unit down is that the compass screen surface that the lower unit screen cloth constitutes in the lower unit seal casinghousing is that herringbone is arranged; Between last unit seal casinghousing and lower unit seal casinghousing, there is the unit flexible seal ring to connect.The concrete characteristics of this programme also have, have below the seal casinghousing both sides, last unit by on unit discharge nozzle flexible seal ring connection on sieve unit material loading discharge nozzle.In the bottom of lower unit seal casinghousing lower unit oversize discharge nozzle and the lower unit minus mesh tapping channel that is connected by lower unit discharging flexible seal ring arranged, lower unit oversize discharge nozzle also has flexible seal ring with lower unit minus mesh tapping channel and being connected of next stage sieve unit.On in described sieve unit sieve unit on have sieve unit blanking dividing plate to link to each other in the unit seal casinghousing with the sieve unit blanking channel.Described upward unit screen cloth and lower unit screen cloth are to be connected to form from beginning to end by a plurality of vibration screens.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, by one in last unit seal casinghousing on the compass screen surface splayed that constitutes of unit screen cloth arrange sieve unit and the compass screen surface that the lower unit screen cloth constitutes in the lower unit seal casinghousing is that the following sieve unit that herringbone is arranged is formed a sieve unit, be arranged above and below by a plurality of sieve unit and form multistage sieve, perhaps, by a plurality of sieve unit and following sieve unit or on sieve unit be arranged above and below and form multistage sieve; Between last unit seal casinghousing and lower unit seal casinghousing, there is the unit flexible seal ring to connect.This structure, arrange because a plurality of sieve unit are solids up and down, so whole screening plant can take ground less, the compass screen surface that constitutes owing to each sieve unit screen cloth is that splayed or herringbone are arranged again, the path that this has just increased material screening can be multiplied screening efficiency.In addition, each sieve unit all has seal casinghousing, all there is flexible seal ring to be connected between each seal casinghousing and between seal casinghousing and each discharging opening, so whole screening process all is to carry out in the environment of a sealing, therefore, the dust that produces in screening process just can not be diffused into outside the screening plant, guarantee the cleaning of working site environment, more met environmental protection requirement.This shows, the utility model compared with prior art, have substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
